IMPROVEMENT IN CONNECTING-RODS.

Specification forming part of Letters Patent No. 128,831, dated July 9,1872- vania.

In the accompanying drawing, Figure 1 is a side view of an improvedconnecting-rod.

Fig. 2 is an edge view of the same. Fig. 3 is an edgc'view of the same,the bolts, lowerstraps, and brasses being removed.

Similar letters of reference indicate corresponding parts.

My invent-ion has for its object to furnish an improved connecting-rod,which shall be so constructed that it may take up the wear withouthaving its length changed, and which shall be simple in construction andconveniently adjusted; and it consists in the constructionandcombination of the various parts of the connecting-rod, as hereinaftermore fully described.

A is the rod. B is the long or inner strap which passes around one endand along the side edgesof the rod A. (l is the short strap that passesaround the other end of the rod A, and the ends of which overlap theends of the long strap B. The straps B O are secured to each other andto the rod A by a gib, D, and key, E, which pass through slots orkeyholes in the straps B G and rod A. F are the inner and G the outerbrasses, that form the bearings for the pins H, and which are held inplace by the straps B G. The key D is secured in place when adjusted bya set-screw, I, which passes in through the rod A, and the forward endof which rests against the side of the key E. J is the bolt which passesthrough the ends of both the straps B O and through the rod A; and K arethe bolts that pass through the long strap B and through the rod A. Theholes inthe rod A, through which the bolts J K pass, are elongated, asshown in Fig. 3, so that the said rod A and the strap B may be moved inopposite directions upon each other, and still be Secured by said bolts.L is a small T-shaped block which is interposed between the inner brassF and the end of the rod A, and against the shoulders of which the endsof the long strap B at all times rest. By this construction the key Ebears against the end of the key-hole or slot in the long strap B, andalso bears against the block L. The gib D bears against the end of thekey-hole or slot in the short strap 0 and the inner endof the key-holein the rod A, so that when the long strap B and the short strap 0 aredrawn together by driving in the key E, drawing the outer brasses Ginward, the rod A and block L are pushed apart, pushing the innerbrasses outward, so that the rod will always have the Same length; or,in other words, the axis of the pins H will always be at the samedistance apart.

Having thus described my invention, I claim as new and desire to secureby Letters Paten t-- In combination with the rod A, provided with theseveral transverse slots, as specified, the long strap B, short strap 0,bolts K, block L, brasses F G, gib D, and wedge E, all constructed andarranged, as shown and described, to provide for the requisiteadjustment of the brasses without changing the distance between theshafts H, as set forth.
